The fact that a private company like Facebook knows a lot about you is not a problem as long as the company has a privacy policy and can be held accountable. The problem specifically is government access to the data. Unlike governments, companies like Facebook have never morphed into tyrannies. Facebook does not tax people, it does not prosecute, it does not put people in prison or fine them, it does not drone people, it does not go to war. Unlike Edward Snowden, an ex-Facebook employee who reveals Facebook's secret illegal activities does not have to fear for his life and take refuge in Russia.
